MSK: Developmental Dysplasia of the Hip: Free MSRA Podcast

🎙️Deep Dive:Developmental Dysplasia of the Hip (DDH)Didyou know that DDHaccounts for nearly a third of hip replacements in people under 60? 🦴 That’s huge. In this revision-packed episode,we’re breaking down everything you need to know about Developmental Dysplasia of the Hip for your MSRA exam prep —from newborn screening to long-term complications. Whether you're a GP traineeor brushing up your MSK, this is essential listening. 🎧📚 🧠What You'll Learn• What DDH is andwhy it’s called “developmental”• The range ofseverity — from mild instability to full dislocation• Why firstborn females in breech are red flags 🚩• How to identifysigns at different ages (from hip clicks to waddling gaits)•Which exam manoeuvres (🩺 Ortolani, Barlow, Galeazzi) are key• When to use ultrasound vs X-ray• When to use the Pavlik harness vs when surgery is needed• What can go wrong— from redislocation to avascular necrosis• Whyswaddling techniques matter for prevention 👶🌀 📌High-Yield Mnemonics💡DDH = DevelopingDisplacing Hips→ It’s a spectrum that can evolve after birth.💡Firstborn femalesfrom native Eastern vermin→ Summarises keyrisk groups:• Firstborn• Female• Native American/Eastern European• Vermin = Mechanical pressures, hormones,restricted movement, neuro issues💡CLUE – Clinical features in infants:• Clicks or clunks (Barlow/Ortolani)• Limited abduction• Unequal leg length• Extra folds (asymmetrical skin creases) 🧪Clinical Pearls• Ortolani “in”(reduces), Barlow “out” (dislocates)• Galeazzi testhelpful for unilateral cases• Left hip is morecommonly affected• Bilateral DDH canbe missed if you’re only looking forasymmetry•Don’t trust every hip “click”! Not all are pathological 👂• Ultrasound forunder 4–6 months, then X-ray post-ossification 🩺Management Strategy✅ Pavlik harness first line if under 6 months✅ Mild dysplasia may self-resolve✅ Closed reduction + casting if Pavlik fails✅ Open reduction + osteotomy for older children❗ Early treatment = best outcomes❗ AVN risk increases with late or forcefulintervention 📉Complications to Know• Avascular necrosis(5–15% post-op risk)• Earlyosteoarthritis• Limp, abnormalgait• Recurrentdislocation• Long-termdisability, need for early hip replacement• Emotional andphysical impact if diagnosis missed 📚Essential MSRAResources for DDH📝Revision Noteshttps://www.passthemsra.com/topic/development-dysplasia-of-the-hip-revision-notes-2/📇Flashcardshttps://www.passthemsra.com/topic/development-dysplasia-of-the-hip-flashcards-2/📂Accordion Q&ANoteshttps://www.passthemsra.com/topic/development-dysplasia-of-the-hip-ddh-accordion-qa-notes/🧪Rapid Fire Quizhttps://www.passthemsra.com/topic/development-dysplasia-of-the-hip-rapid-quiz-2/🎯Quiz Accesshttps://www.passthemsra.com/quizzes/development-dysplasia-of-the-hip/🧠 More revision tools: https://www.passthemsra.com🎁 Free practice: https://www.freemsra.com 💬MSRA Self-TestPromptsWhich newborns should be referred for early hip ultrasound?How do Ortolani and Barlow tests differ in their mechanics and findings?When do you switch from ultrasound to X-ray in DDH?What are the red flags for missed or late-diagnosed DDH?What is the key complication of delayed reduction? 📍Final ThoughtDDHmay begin quietly, but if missed, it can cause lifelong functional issues and early arthritis.Recognising those early clues and intervening appropriately can change achild’s entire future. It also makes you wonder — what other childhoodconditions hinge on something as simple as how we wrap a baby’s legs? 🤔💡 #MSRA #MSRARevision#MSRAOrthopaedics #DevelopmentalDysplasiaoftheHip #DDH #PavlikHarness#MSRAFlashcards #MSRAQuiz #MSRAQandA #PassTheMSRA #FreeMSRA #HipDislocation#NewbornScreening #BreechBirth
